Summary

Closes #583

Reworks OIDC login to resolve identity by (issuer, subject) instead of username, closing an account-takeover-shaped bug where an OIDC-asserted username colliding with an existing local account would silently log in as that account. Builds a general-purpose linked-identity model on top of that fix and extends it to two new secondary login providers.

  • Identity model: new user_identities table keyed on (provider_type, provider_key, subject). First-time OIDC logins whose derived username collides with an existing different account get auto-suffixed instead of linked. Returning logins are matched by identity, never by username, so profile/claim changes at the IdP can't rename or re-provision the account.
  • User lifecycle: users.status (active/suspended/disabled), enforced at session lookup and every login path (local, OIDC, proxy), and in the weekly-flow scheduler and inbox refresh so suspended users' jobs stop running. Admin-settable from Settings → Users, with immediate session invalidation on suspend/disable.
  • Bootstrap admin protection: users.is_protected marks the onboarding-created admin, exempting them from automatic OIDC role sync and blocking self-suspension.
  • Role source tracking: users.role_source (local|oidc) — only the env-var-configured OIDC provider can ever set it to oidc.
  • Google and Plex as secondary login methods: both are structurally link-only — they can never provision a new account or grant a role. Google is a settings-backed OAuth client (fixed issuer, admin configures client id/secret/redirect URI). Plex reuses the existing PlexClient/plexConnectionStore PIN-OAuth flow, now also registering a login identity when a user connects their own account.
  • Explicit linking + reauth: generic identity link/unlink API with lockout protection (can't remove your last usable sign-in method). Sensitive linking actions require a session reauthenticated within the last 15 minutes (new sessions.reauthenticated_at column and POST /api/auth/reauth, since session creation time alone can't re-arm for long-lived sessions).
  • token_endpoint_auth_method now defaults to client_secret_basic per OIDC Core's stated default, configurable via OIDC_TOKEN_ENDPOINT_AUTH_METHOD; previously always sent client_secret_post regardless of what the IdP required.
  • SSO-only mode: optional flag to hide the local login form by default, with a manual "sign in with a local account instead" link so local accounts, including the recovery admin, are never fully hidden.

Frontend: Connected Accounts panel in Settings → Account, Google/Plex buttons and SSO-only handling on the login page, Google OAuth config and Plex login toggle in admin settings, status editor in Settings → Users.

Known gap: toggling Google/Plex login off does not scan for users who would be orphaned by it (only the per-user unlink endpoints do). Worth adding if these providers see real usage.

Test plan

  • npm test — 560/564 unit tests pass (4 pre-existing failures unrelated to this change, caused by missing ffmpeg in the sandbox test environment, not by this PR)
  • npm run test:integration — 41/41 pass, including new coverage for identity link/unlink, lockout protection, reauth gating, Google login (link-only enforcement, conflict detection, suspended-user rejection), and Plex login gating
  • Frontend tests (.tests/frontend) — 46/46 pass
  • npm run lint / npm run lint:backend — clean
  • vite build — clean production build
  • Manual container build/boot verified via a local Podman image built from this branch

Reworks OIDC login to resolve identity by (issuer, subject) instead of
username, closing an account-takeover-shaped bug where an OIDC-asserted
username colliding with an existing local account would silently log in
as that account. Builds a general-purpose linked-identity model on top
of that fix and extends it to two new secondary login providers.

- Identity model: new user_identities table keyed on
  (provider_type, provider_key, subject). First-time OIDC logins whose
  derived username collides with an existing different account get
  auto-suffixed instead of linked. Returning logins are matched by
  identity, never by username, so profile/claim changes at the IdP
  can't rename or re-provision the account.

- User lifecycle: users.status (active/suspended/disabled), enforced
  at session lookup and every login path (local, OIDC, proxy), and in
  the weekly-flow scheduler and inbox refresh so suspended users' jobs
  stop running. Admin-settable from Settings -> Users, with immediate
  session invalidation on suspend/disable.

- Bootstrap admin protection: users.is_protected marks the
  onboarding-created admin, exempting them from automatic OIDC role
  sync and blocking self-suspension.

- Role source tracking: users.role_source (local|oidc) - only the
  env-var-configured OIDC provider can ever set it to oidc.

- Google and Plex as secondary login methods: both are structurally
  link-only - they can never provision a new account or grant a role.
  Google is a settings-backed OAuth client (fixed issuer, admin
  configures client id/secret/redirect URI). Plex reuses the existing
  PlexClient/plexConnectionStore PIN-OAuth flow, now also registering
  a login identity when a user connects their own account.

- Explicit linking + reauth: generic identity link/unlink API with
  lockout protection (can't remove your last usable sign-in method).
  Sensitive linking actions require a session reauthenticated within
  the last 15 minutes (new sessions.reauthenticated_at column and
  POST /api/auth/reauth, since session creation time alone can't
  re-arm for long-lived sessions).

- token_endpoint_auth_method now defaults to client_secret_basic per
  OIDC Core's stated default, configurable via
  OIDC_TOKEN_ENDPOINT_AUTH_METHOD; previously always sent
  client_secret_post regardless of what the IdP required.

- SSO-only mode: optional flag to hide the local login form by
  default, with a manual "sign in with a local account instead" link
  so local accounts, including the recovery admin, are never fully
  hidden.

Frontend: Connected Accounts panel in Settings -> Account, Google/Plex
buttons and SSO-only handling on the login page, Google OAuth config
and Plex login toggle in admin settings, status editor in Settings ->
Users.

Known gap: toggling Google/Plex login off does not scan for users who
would be orphaned by it (only the per-user unlink endpoints do). Worth
adding if these providers see real usage.

📝 Walkthrough

Walkthrough

The pull request adds Google authentication, linked identity management, Plex PIN login, OIDC identity resolution, account status controls, session reauthentication, protected-account rules, and frontend settings and login flows.

Changes

Authentication and identity management

Layer / File(s) Summary
Account state and session enforcement
.tests/auth/proxy-auth.test.js, .tests/helpers/backendTestHarness.js, backend/config/*, backend/db/helpers/*, backend/middleware/*, backend/routes/onboarding.js, backend/services/inboxService.js, backend/services/weeklyFlow/weeklyFlowScheduler.js
Users and sessions now store account status, protection, role source, local-password state, linked identities, and reauthentication timestamps. Inactive users lose session access, proxy access, inbox refreshes, and scheduled flow processing.
Google and OIDC authentication
.tests/auth/google-auth.test.js, .tests/auth/oidc-auth.test.js, backend/routes/auth.js, backend/server.js, backend/services/googleAuth.js, backend/services/oidcAuth.js
Google OIDC login and linking use PKCE, state, nonce, discovery, callback exchanges, and linked identities. OIDC resolution now supports stable issuer/subject lookup, username collision suffixing, protected accounts, suspended-account rejection, and configurable token authentication.
Identity linking and Plex authentication
.tests/users/identity-link-routes.int.test.js, .tests/users/plex-link-routes.int.test.js, backend/routes/auth.js, backend/routes/users.js, backend/routes/users/identityLinkHandlers.js, backend/routes/users/plexLinkHandlers.js
Authenticated users can list and remove linked identities. Recent authentication and fallback-method checks protect unlinking. Plex login and self-linking validate configuration, ownership, account status, and session requirements.
Frontend sign-in and account settings
frontend/src/pages/Login.jsx, frontend/src/pages/SsoComplete.jsx, frontend/src/pages/Settings/..., frontend/src/utils/api/endpoints/auth.js, frontend/src/utils/reauth.js, frontend/src/index.css
The frontend supports conditional OIDC, Google, and Plex sign-in, SSO-only mode, Google integration settings, connected-account management, Plex reauthentication, user status controls, and authentication API calls.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 995d2

The PR adds identity, lifecycle, and authentication changes, but administrators can still reset any account’s password through the user-management endpoint without recent reauthentication. A stale admin session could enable account takeover, so the PR is not merge-ready until this protection is added.

Inline comments:
In @.tests/auth/oidc-auth.test.js:
- Around line 535-548: Update the cleanup in the post-authentication-method test
around createPendingOidcLogin and completeOidcLogin to delete
OIDC_TOKEN_ENDPOINT_AUTH_METHOD in the finally block, ensuring the environment
is restored before later tests run.

In `@backend/routes/onboarding.js`:
- Around line 183-190: Update the bootstrap account creation flow around
userOps.createUser and userOps.setProtected so protection is persisted
atomically with the initial insert, or wrap both writes in a transaction that
aborts onboarding when protection fails; do not ignore the protection write
result, and ensure onboarding cannot complete with an unprotected bootstrap
admin.

In `@backend/routes/users.js`:
- Around line 305-315: Update the status-change guard in the user update handler
so every protected recovery account rejects non-active statuses, not only when
the requesting administrator is the same user; preserve any explicitly
authorized recovery-account transition path, and ensure rejected changes do not
reach updates.status or deleteSessionsByUserId.

In `@backend/routes/users/plexLinkHandlers.js`:
- Around line 202-221: Update the admin DELETE /:id/plex-link handler to remove
the user’s Plex identity after clearing the connection. Use
userIdentityOps.getForUser(id) to find the identity whose providerType is
"plex", then unlink it via userIdentityOps.unlink when present, while preserving
the existing cleanup and response behavior.

In `@backend/services/googleAuth.js`:
- Around line 182-201: Update the pending.mode === "link" branch in the Google
authentication flow to reject linkUser when its status is not "active", before
checking or creating the identity link. Match the login path’s inactive-account
handling and preserve the existing missing-user behavior and linking logic.

In `@backend/services/oidcAuth.js`:
- Around line 234-246: Wrap createSystemProvisionedUser, userOps.updateUser, and
userIdentityOps.link in the same SQLite transaction, using the existing
transaction mechanism and ensuring all three operations share its database
context. Preserve the current validation and error propagation so any link
failure, including a uniqueness conflict, rolls back the newly provisioned user
and role update.
- Around line 203-224: Sanitize users before callback-exchange responses leave
the services, removing sensitive fields such as passwordHash. In
backend/services/oidcAuth.js lines 203-224, apply the sanitized user payload
helper to results from resolveOidcSessionUser in both existing-identity and
provisioning paths; in backend/services/googleAuth.js lines 244-257, sanitize
pending.result.user in both the link and session branches of
exchangeGoogleCallback.
- Around line 103-120: Update getRequiredConfig() to permit an empty
OIDC_CLIENT_SECRET when getTokenEndpointAuthMethod() returns none, while
retaining the required-secret validation for secret-based methods. Update
buildClientAuthentication() to accept only client_secret_basic,
client_secret_post, and none, and throw a clear error for any unsupported method
instead of defaulting to ClientSecretBasic.

In `@frontend/src/pages/Login.jsx`:
- Around line 52-53: Update the Login flow around startPlexLoginPin to open a
blank Plex authorization popup synchronously before awaiting the API request,
then navigate that popup to authUrl once the request completes. Handle a null
window.open result with an actionable error and avoid continuing into polling
without a usable authorization window.

In `@frontend/src/pages/Settings/components/ConnectedAccountsSection.jsx`:
- Around line 26-34: Update the load flow in ConnectedAccountsSection so
failures from getMyIdentities are stored in component state instead of being
swallowed. Render an error or retry state when that failure is present, rather
than treating the initial empty identities list as a successful empty result;
preserve the existing loading reset and successful identity handling.

In `@frontend/src/pages/Settings/components/PlexSelfLinkSection.jsx`:
- Around line 63-69: Update the polling error handling around
isReauthRequiredError and promptReauth to stop immediately for cancellation,
repeated reauthentication errors, provider errors, and declined
reauthentication; use the shared popup cleanup, then surface the actual failure
message instead of allowing the generic timeout path. Preserve retry behavior
only for the first reauthentication error when promptReauth() returns true.

In `@frontend/src/pages/Settings/components/SettingsConnectTab.jsx`:
- Around line 706-709: Update the Redirect URI hint in SettingsConnectTab to
construct the callback URL with the frontend’s existing base-path helper,
matching buildApiUrl’s path handling instead of using window.location.origin
alone. Preserve the /sso/google/callback suffix and ensure the displayed URI
includes any configured application sub-path.

In `@frontend/src/pages/Settings/components/SettingsUsersTab.jsx`:
- Around line 333-344: Update the SSO-only onChange handler to catch
handleSaveSettings failures visibly instead of suppressing them, and restore or
refetch the prior security.ssoOnly value when persistence fails. Keep the
optimistic update on success and use the existing settings/error-reporting
mechanisms.

- Sanitize user payloads returned from OIDC/Google exchange so
  passwordHash never leaves the service layer.
- Admin DELETE /:id/plex-link now removes the user's Plex login
  identity too, not just the connection - previously Plex sign-in
  survived an admin disconnect.
- Protected recovery accounts can no longer be suspended/disabled by
  any admin, not just blocked from suspending themselves.
- Google account linking now rejects a suspended target user, matching
  the login path.
- OIDC first-time provisioning (create user, set role source, link
  identity) is now one transaction, so a concurrent duplicate-subject
  race can't leave an orphaned unlinked user behind.
- Bootstrap admin protection is set atomically in the same insert as
  account creation instead of a separate best-effort update.
- token_endpoint_auth_method now supports "none" with an empty client
  secret for public clients, and rejects unrecognized values instead
  of silently falling back to client_secret_basic.
- Test hygiene: OIDC_TOKEN_ENDPOINT_AUTH_METHOD is cleared between
  tests so it can't leak into unrelated cases.
- Frontend: open the Plex login popup synchronously so browsers don't
  block it as an unsolicited popup; surface identity-load failures
  instead of rendering them as "no accounts connected"; stop Plex-link
  polling on non-reauth errors instead of falling through to a generic
  timeout; base-path-aware Google redirect URI hint; report and revert
  the SSO-only toggle on a failed save instead of swallowing the error.

Adds regression coverage for the security-relevant fixes: exchange
payload sanitization, admin unlink removing the identity, protected
account guard against other admins, suspended-user link rejection,
and the none/unknown auth-method handling.

…de path

- Plex login is now transaction-cookie-bound like the OIDC and Google
  flows: /pin stores the pinId/code/clientId server-side keyed by a
  random transaction ID delivered only via an HttpOnly cookie, and
  returns just authUrl to the client. Previously /complete accepted a
  bare pinId/code/clientId tuple from the request body with no binding
  to the browser that started the flow, so an attacker could initiate
  a PIN, send the resulting authUrl to a victim, and poll /complete
  themselves to receive the victim's Aurral session once they
  authorized it. Also restricts forwardUrl to same-origin relative
  paths instead of passing an arbitrary caller-supplied URL through to
  plex.tv.

- Existing OIDC users no longer get orphaned on upgrade. Every account
  that existed before user_identities was introduced is now marked
  needs_identity_migration. On first post-upgrade OIDC login, if the
  claimed username matches such an account that's never been linked
  to anything, has no known local password, and isn't the protected
  bootstrap admin, the identity is linked to that existing account
  instead of provisioning an unreachable "username-2" duplicate that
  strands the user's flows, history, and preferences on an account
  nobody can sign back into.

- Corrected the has_local_password backfill from true to false for
  pre-existing accounts. Marking JIT-provisioned legacy accounts as
  having a real known password was the unsafe direction: it would let
  such an account be told it has a password fallback and be allowed
  to remove its only real way in, a genuine lockout. Defaulting to
  false only costs a real local-password account an occasional
  "sign in again" prompt instead.

- DELETE /me/plex-link now requires a recent reauth, matching the
  generic identity-unlink route it duplicates the effect of - it was
  previously reachable with only a stale session, bypassing the
  reauth control entirely via the Plex-specific endpoint.

Adds regression coverage for all three: transaction-cookie enforcement
and forwardUrl validation on Plex login, legacy account adoption
(including the negative cases - real password, already linked,
protected admin), and the Plex unlink reauth requirement.
Follow-up review found the previous legacy-adoption gate was ineffective:
the migration backfills has_local_password to false for every
pre-existing row, so the "no known local password" condition guarding
adoption was vacuous for exactly the accounts it was meant to protect.
Any OIDC identity whose username matched a non-protected local account
could take it over, reopening the hole this branch exists to close.

- Adoption now requires an admin to explicitly approve each account
  (new allow_identity_adoption column, never backfilled). The approval
  is consumed by the first sign-in that uses it. Legacy accounts show
  a "no SSO identity" / "awaiting SSO claim" badge in Settings > Users,
  and the protected recovery admin can never be approved.

- POST /me/password now requires a recent auth. An account with no
  known local password skips current-password verification, so without
  this a stolen long-lived session could set a password outright. A
  successful local login also records that a password exists, which
  self-heals migrated rows and re-arms both the lockout check and
  current-password verification.

- forwardUrl validation no longer accepts backslashes or control
  characters, and confirms the value still resolves to the base origin
  once parsed. "/\evil.example/steal" passed the previous check but
  normalizes to an off-origin URL.

- The none token-endpoint auth method test now asserts client_id is
  present in the request body, not just that credentials are absent.

Also fixes editStatus never being passed through SettingsPage, which
left the user status dropdown non-functional, and documents the
migration flow, its ordering trap and recovery, and the
OIDC_TOKEN_ENDPOINT_AUTH_METHOD variable.

Found a couple more issues while running further checks and testing some legacy-migration scenarios. Turns out the account-adoption gate from the last commit didn't actually do anything. The migration backfills every pre-existing account as passwordless, so the "no known password" check it relied on was always true and never blocked a takeover. Adoption now needs explicit admin approval per account instead, plus a couple smaller reauth/validation tightenings found along the way.

Sorry about the size.

Admin password resets bypass the new recent-authentication requirement.

Line 548 protects the self-service password change with requireRecentAuth(). The admin branch here sets updates.passwordHash on PATCH /:id without any recency check. An attacker who holds a stolen but stale admin bearer token can therefore reset any account password, including another administrator's, and then sign in as that user. The recency control added for /me/password gives no protection on this path.

Apply requireRecentAuth() to the route, or require a recent reauthentication before the handler accepts password for another user.

🔒 Proposed fix
-router.patch("/:id", requireAuth, async (req, res) => {
+router.patch("/:id", requireAuth, async (req, res) => {

Add the check inside the admin branch, before the hash is written:

if (password && !isSelf) {
  const recent = assertRecentAuth(req); // reuse the requireRecentAuth session check
  if (!recent) {
    return res.status(401).json({
      error: "reauth_required",
      message: "Please confirm your credentials to continue",
    });
  }
}

res.setHeader("Set-Cookie", ...) replaces every Set-Cookie value already set on the response. If any middleware sets a cookie before this call, that cookie is lost.

388-391: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Make the column addition and the backfill atomic.

The ALTER TABLE and the UPDATE run as two separate statements. If the process stops between them, the next boot sees needs_identity_migration present and skips the backfill. Existing accounts then stay at 0 and never show as legacy accounts in the adoption workflow.

Wrap both statements in a transaction so the backfill cannot be lost.

 if (!userColumns.includes("needs_identity_migration")) {
-  tryAddColumn("ALTER TABLE users ADD COLUMN needs_identity_migration INTEGER NOT NULL DEFAULT 0");

- Admin password resets for other users now require a recent
  reauthentication, matching the self-service password change path. A
  stolen but stale admin token could previously reset any account's
  password, including another admin's.
- Plex login's transaction cookie is now appended rather than set,
  since setHeader("Set-Cookie", ...) silently dropped any cookie
  already queued by earlier middleware.
- needs_identity_migration column add + backfill now run in a single
  transaction so an interrupted boot can't leave legacy accounts
  permanently unflagged.
- Recovery docs no longer assume the duplicate account created on
  first SSO login always gets a "-2" suffix; it's the first available
  numeric suffix.
- The "Claim by SSO sign-in" toggle in Settings > Users is now gated
  on SSO being enabled, matching the badge condition it's paired
  with.
- refreshAuth() now reports whether the bootstrap refresh succeeded;
  a failed refresh after Plex login clears the stored token and shows
  an error instead of leaving the user in a silent stuck state.

Comment thread frontend/src/contexts/AuthContext.jsx
refreshAuth() now returns an explicit boolean, but SsoComplete's
refreshed !== null check treated both true and false as success, so a
failed bootstrap refresh after OIDC/Google sign-in still silently
navigated to / instead of showing an error, the same gap already
fixed on the Plex login path.
…before the migration flag existed

The needs_identity_migration backfill flagged every pre-existing user
row unconditionally, including accounts provisioned by the OIDC login
flow itself before that column existed. Those accounts already had a
linked row in user_identities, so resolveOidcSessionUser always took
its fast "existing identity" path on login - the only path that
clears needs_identity_migration/allow_identity_adoption is the legacy
adoption branch, which an already-linked identity can never reach.
The account was permanently stuck showing "awaiting SSO claim" no
matter how many times the admin toggled approval or the user signed
in again.

Narrows the one-time backfill to rows with no linked identity, and
adds an unconditional reconciliation pass that runs on every boot to
clear the flags for any row that already has one - this is what
actually repairs a database that already went through the old
backfill, since the one-time migration block only runs once per
column addition.
The admin edit-user save handler had no handling for the
reauth_required response added when resetting another user's
password now requires a recent reauth. Without this, an admin
whose session had aged out would just see a bare "reauth_required"
error toast with no way to actually complete the reset, since
nothing prompted for the password. Wires in the same
isReauthRequiredError/promptReauth retry pattern already used by the
self-service password change and Plex/Google linking flows in this
file.
…omits profile claims

Some providers (Authelia among them) don't guarantee username/email/
group claims in the ID token itself, only from the UserInfo endpoint,
per the OIDC Core spec allowing this. Aurral only ever read claims
from the ID token, so those providers hit "OIDC identity did not
include a usable username" even on a fully valid login.

After the token exchange, fetch UserInfo (scoped to the ID token's
already-verified subject) and merge it over the ID token claims
before resolving username/role/display name. If UserInfo fetch fails
or the provider doesn't advertise the endpoint, falls back to the ID
token claims exactly as before, so existing working setups are
unaffected.

Credit to hrenard for finding and root-causing this in PR lklynet#610 against
the pre-identity-model version of this file; folding the same fix into
this branch since the identity rework significantly changed the
surrounding code.
